This guide compares gas, electric, and infrared heating options for events held in England and Wales. Selecting the correct outdoor heater hire equipment depends on the size of the space, power availability, and the duration of the event.

Gas Patio Heaters

Gas patio heaters are a common choice for events where mains electricity is unavailable or limited. These units typically run on propane gas cylinders housed within the base of the unit.

Heat Output and Coverage

Most standard gas patio heaters provide between 10kW and 13kW of heat. They project heat in a circular radius, typically warming an area of approximately 3 to 5 metres in diameter. Because they rely on convection, the heat rises, making them most effective in open-air settings rather than under low-hanging structures.

Operational Considerations

  • Fuel: Propane cylinders are heavy and require manual replacement.
  • Portability: Units are often fitted with wheels, but moving them while lit is prohibited.
  • Safety: These heaters must be used in well-ventilated areas. They should never be used inside marquees or enclosed tents due to carbon monoxide risks.

Electric Free-standing Heaters

Electric free-standing heaters are suitable for indoor-outdoor spaces like covered terraces or semi-enclosed marquees. They require a reliable power source, often necessitating a generator if the event location lacks high-amperage sockets.

Performance and Efficiency

Electric heaters provide consistent heat without the need for fuel refills. They are generally quieter than gas alternatives and do not produce fumes. Output is usually measured in watts, with most commercial units operating between 2kW and 3kW.

When to Use

These units are practical for events where safety regulations prohibit open flames. Because they do not emit carbon monoxide, they are safer for use in semi-enclosed areas, provided the electrical load is managed correctly.

Infrared Heaters

Infrared heaters function differently from gas or convection electric heaters. Instead of heating the air, they emit electromagnetic radiation that warms people and objects directly.

Advantages of Infrared

Infrared technology is highly efficient for outdoor events because wind does not dissipate the heat as easily as it does with convection heaters. If guests are seated at a 6ft round banqueting table, infrared heaters can be positioned to direct warmth specifically at the seating area.

Coverage and Limitations

Infrared heaters provide immediate warmth upon switching on. However, the heat is directional. If guests move outside the direct beam of the heater, they will feel the ambient air temperature immediately. This makes them ideal for fixed seating arrangements rather than standing receptions.

Calculating Heater Requirements

Determining the number of heaters required for an outdoor event involves calculating the square footage of the area and the ambient temperature. As a practical rule of thumb, one 12kW gas heater covers approximately 20 to 25 square metres in moderate conditions.

General Estimation Guide

  • Mild weather (15°C+): 1 heater per 30 square metres.
  • Cool weather (10°C - 15°C): 1 heater per 20 square metres.
  • Cold weather (below 10°C): 1 heater per 15 square metres.

When planning your layout, consider the placement of white folding chair hire items and other equipment to ensure heaters are not obstructed. Proper spacing is essential to prevent hot spots and ensure even distribution.

Safety and Compliance

Safety is the primary factor when arranging outdoor heater hire. Regardless of the type, all equipment must be positioned on a level surface to prevent tipping. For gas models, ensure the hose and regulator are checked for leaks before use.

Electrical Safety

When using electric or infrared heaters, avoid daisy-chaining extension leads. High-wattage equipment requires dedicated circuits to prevent tripping breakers. If you are hiring catering equipment alongside heaters, ensure your power distribution plan accounts for the combined load of all appliances.

Choosing the Right Equipment for Your Venue

The choice between gas and electric depends on the infrastructure of your venue. If you are hosting an event in a field or a remote location, gas is the most practical solution. If you are hosting on a patio or in a marquee, electric or infrared options are often preferred for their cleanliness and ease of operation.

Frequently asked questions

Can I use gas patio heaters inside a marquee?

No. Gas patio heaters produce carbon monoxide and pose a significant fire risk. They must only be used in open-air environments. For marquee heating, use electric or infrared units designed for enclosed spaces.

How many gas heaters do I need for a 100 square metre area?

In moderate weather conditions, you should allow for four to five 12kW gas heaters to maintain a comfortable temperature across 100 square metres.

Do infrared heaters work in the wind?

Yes. Because infrared heaters warm objects and people directly rather than heating the air, they are significantly more effective than gas convection heaters in windy conditions.

Do I need a generator for electric heater hire?

If the venue does not have sufficient power outlets, a generator is required. Always check the total wattage of the heaters against the capacity of your power supply before confirming your order.
